This is the best buffer on the market today for AR style rifles! Reduce felt recoil, improve reliability, reduce bolt carrier speed, reduce wear on parts, reduce vibration and shock to optics, and suppress bolt bounce with this simple drop-in replacement. This buffer has a piston that is hydraulically dampened to absorb the shock of impact from the bolt carrier on its rearward motion and to prevent bolt bounce when it chambers a new cartridge. You will feel less recoil and smoother operation with this buffer!

Replaces buffers that are 3.25" in length. Designed for 7.62mm/.308 cal AR style rifles with an AR-10 length collapsible stock tube which is 3/4" longer than an AR-15 stock tube. If you use an AR-15 carbine stock tube on your .308 rifle, then you would use the short 2.5" buffer model instead. Works with Armalite, LMT, Sig, Noveske and LWRCI .308 rifles with collapsible stocks and any others that use the longer collapsible stock tube. Replaces factory .308 buffers that are 3.25" in length.
